orcinus documented the Chronoduino:
It’s a wiki with all the relevant info and data concerning Chronoduino, including the EAGLE files and all the datasheets. The software section is still missing, but (current) hardware should be all there.
I’ve also finished revision 0.3 of the main board, containing a bunch of power supply changes, and sent the files off for fabrication. Rev. 0.3 should be able to draw power from the battery, micro USB, the serial TTL header or the SPI header, whichever of these is connected. I’ve also added a tiny charging status LED (since the charging IC supports it anyway and there was space), fixed the useless debug LED, ditched the JST connector and reshaped the battery connector pads so either the wires can be soldered to them directly, or a right-angle SMD 2-pin header, and did a few other changes that escape me right now.

looks great, something about the thickness (headers) should be done.
